MBIMR15) corresponding to the mailbox interrupt mask register (MBIMR) and interrupt mask
register (IMR), interrupts may be sent to the CPU.
However, a transmit wait message cannot be canceled at the following times:
• During internal arbitration or CAN bus arbitration
• During data frame or remote frame transmission
Figure 18.10 shows a flowchart for transmit message cancellation.
